The maximum length of arguments in a shell command is dependent on the underlying operating system and the system’s configuration. In most cases, the maximum length of arguments in a shell command is determined by the operating system’s shell and the maximum size of a command line buffer.
In most Unix-like systems, the maximum length of a command line buffer is defined by the ARG_MAX
constant, which can be determined by using the getconf
command:
getconf ARG_MAX
This will return the maximum length of arguments and environment variables for a single command, in bytes.
For example, on a typical Linux system, the value of ARG_MAX
is usually around 262144
bytes, which translates to a maximum length of command line arguments of around 255 KB
.
However, this value can vary between different operating systems and configurations, so it’s best to check the ARG_MAX
value on the specific system you are working with to determine the maximum length of arguments in a shell command.
